What is the top 10 list of reddit subscribers for cryptocurrency subreddits as of 2018 May?

Is there a list of the top 10 subscribed subreddits related to cryptocurrency? I know r/bitcoin and r/cryptocurrency is the top two at 800k and 600k. I believe this is a good gauge if a cryptocurrency is growing organically vs reading hyped up articles with the illusion of a fake community following for some cryptos. Or is there a better metric to gauge this?
